Reduces morbidity from skeletal metastases in breast cancer patients during long-term bisphosphonate (apd) treatment

131 patients with osteolytic metastases from breast cancer were randomised to receive long-term oral treatment with aminohydroxy-propylidene-bisphosphonate (APD), 300 mg daily (n = 70), or to act as controls (n = 61) in a multicentre trial. Specific antitumour therapy was at the discretion of the clinician and variable. An interim analysis was made after a median follow-up of 13 months in the APD group and 14 months in the controls. There was a significant reduction in pathological fractures and severe bone pain in the APD group, and hypercalcaemia was prevented. Consequently the necessity for radiotherapy for skeletal complications was more than halved; the number of systemic therapy changes was also reduced. Gastrointestinal side-effects of APD led to a drop-out of 8% of patients. Oral supportive APD therapy is simple and convenient, and significantly reduces skeletal morbidity in advanced breast cancer

The natural course of myasthenia gravis: a long term follow up study.

A long term follow up study is presented of 73 patients with myasthenia gravis, living in Amsterdam between 1926 and 1965. In the period 1961-65 the annual incidence was 3.1, the prevalence 53 per million. Maximum severity of the disease occurred during the first seven years after onset in 87%. Eighteen (29%) patients died, of whom eight had a thymoma (TH). Spontaneous improvement or remission occurred at any time during the follow up. At the end of the study (1985) 16 (22%) patients were in a complete clinical remission, 13 (18%) had improved considerably (3 with prednisone), 12 (16%) had improved moderately, 12 (16%) had remained unchanged and two had deteriorated. If the early deaths are excluded the outcome is similar in the early and the late onset group without TH. Patients with TH had a less favourable course. Associated autoimmune diseases were diagnosed in 25% (n = 58). Because most of these patients were treated with anticholinesterases only, the evolution of their clinical state represents the natural course of MG
